Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574346, here are decompositions:

17 + 31574329 = 31574346
19 + 31574327 = 31574346
43 + 31574303 = 31574346
113 + 31574233 = 31574346
173 + 31574173 = 31574346
239 + 31574107 = 31574346
347 + 31573999 = 31574346
379 + 31573967 = 31574346

Showing the first eight; more decompositions exist.
